Study Notes

Cholinergic Antagonists

Tolterodine is a muscarinic blocker used to relieve urinary and bladder difficulties.

Cholinergic Stimulation

Cholinergic stimulation increases the contraction of smooth muscle, increases the secretion of glands, and increases the peristalsis of the digestive tract.

Nicotinic Acetylcholine Receptors

Nicotinic acetylcholine receptors are found in the autonomic ganglia, the neuromuscular junction, and the central nervous system.

Ephedrine

Ephedrine is not a cholinergic agonist, but rather a sympathomimetic amine.

Nasal Decongestants

The use of nasal decongestants is associated with rebound congestion, also known as rhinitis medicamentosa.
